He was absent the day his group picked their book for their English project and they picked Deathly Hallows. He was trying to read the book in class and kept asking other kids "Who's Snape?" "Who's Dumbledore?" and "How do you say this girl's name?" (Hermione)
I did the un-teacher like thing and told him to watch the 1st 6 movies. I didn't think there was any way he was going to read the 6 books in time for the group project and I can't fathom trying to read Deathly Hallows and being able to analyze it for a project without having read/seen the 1st 6 parts of the series. The movies might not perfectly follow the books, but I figured he was still better off than trying to read that book blind and make any sense of it. Some series you can pick up in the middle and be fine. I think Deathly Hallows would have been confusing without the prior knowledge of the first 6 books.
